"Punk 103" is a song from the album Ring n'Roll (BEC 5772833), released in 2011. This track was written and composed by Catherine Ringer, set to music by herself, Mark Kerr, and RZA + Stone Mecca's musicians. The B-side of this vinyl is an exclusive acoustic live version recorded during a Jean-Paul Gaultier private show.

Catherine Ringer is the former singer from the famous French band Les Rita Mitsouko, formed by Fred Chichin (her late husband) and herself. From the hit "Marcia Baila" in 1985 to their last album Variety in 2007, they have worked with the likes of Tony Visconti, Iggy Pop, Sparks, Jesse Johnson, William Orbit and Serj Tankian. In 2009, Catherine decided that it was time to compose and produce her first solo album on her own. In collaboration with Mark Kerr, Azzedine Djelil and Jean-Baptiste Brunhes in her own studio, she recorded different instruments, from piano to drums. She also reworked "Rendez-Vous," a track recorded in 1998 with Coba, the Japanese accordion-player and adapted the "Adagietto" from "Mahler." Housed in a gatefold sleeve, this collector's edition includes a vinyl-etching on side D and a CD of the entire album.
